The Audion 845 Black Shadow single-ended amplifiers employ pure Class-A
circuitry with automatic biasing from the input to the output.
Throughout the amplifier, no overall feedback is incorporated which would reduce
dynamic headroom. All driver and output stages are running in optimized Class-A
The 845 valves utilized in the amplifiers are operating within manufacturers
guidelines, and as such should provide a minimum of 2000 hours tube life,
approximately 2 years in general private use.
Please note
After the amplifier is switched on there will be an initial delay of
approximately 45 seconds to allow the valves to pre-heat, after which time a click
will be heard and the amplifier will come into operation.
Warning
The 845 valve in normal operation has a working temperature of over
100º Centigrade – in no circumstances should the valve be touched during
operation or for at least 15 minutes after the amplifier has been turned off.
